TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No. 625,082, dated May 16,1899.

. Application filed December 14,1898. Serial ITO-699,234. (No model.)

To all whom, it may concern;

Be it known that I, EDWARD E. BAKER, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Type-WVriterOabinets, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is avertical cross-section showing the desk in open position and with thecarrying-table removed, and Fig. 2 is a similar section showing theparts in closed position.

My invention relates to the cabinets or desks which are arranged to holdtype-writers, sewing-machines, or similar articles; and its object is toobtain a simple and effective construction by means of which thecarrying-table for the machine may be held in a substantially horizontalposition when the desk is closed, this carrying-table moving verticallyin substantially parallel planes in opening and closing the desk.

In the drawings, 2 represents a desk having a back 3 and provided with atable-receiving opening which is closed by the sides 4 and an inclinedfront board 5. The front board is rigidly secured in place and forms away and guide for the carrying-table 6, which consists of a box-likestructure having an inclined front face provided with small rollers 7,which travel upon the front board 5 as the carrying-table moves up ordown. Angular links 8 are pivoted to the ends of the carrying box ortable near its top, and the upper arms of these angle-links arepivotally conthe table when in its upper position.

nected with bell-crank levers 9, which are pivoted at 10 to the cabinetat the ends of the cavity receiving the table. The front ends of thesebell-crank levers are pivotally con-. nected to the front portion of thetop section or the front rail 11, secured thereto, and their elbowportions are preferably provided with stop-pins 12, which contact withthe anglelinks 8 when the desk is opened, as shown in Fig. 1, andprevent backward movement of Each end of the carrying table or box ispreferably provided with steadying-pins 13, which are adapted to engagewith the lower horizontal arms of the angle-links 8, thus acting tosteady the upward-and-downward movement of the carrying table or boxWhich-s11 pports the machine.

To the rear end portions of the swinging top section I connect longpivotal links 14, which swing in vertical planes outside the bell-cranklevers and are pivoted to the sides of the recess or cavity at 15.Theselevers may be curved near their lower ends, so that they may notinterfere with the joints between the bell-crank levers and theangle-links.

16 is a counterweight consisting of a bar of metal secured to the rearportion of the coversection, and 17 is a sliding shelf or board uponwhich the machine rests.

It is evident that with the construction shown when the cover-section istilted back wardl y from the closed position shown in Fig. 2 thiscover-section will swing through an arc whose center is constantlychanging, and during this movement the bell-crank levers and their linkconnections with the carrying-table will lift this table upwardly intothe position shown in dotted lines in Fig. 1, it bein g guided in itsmovement by the front board 5, along the inner face of which it ismoved. When thus brought into the open position, the sliding board uponwhich the type-writer or other machine rests may be pulled forward tothe point desired.

The advantages of my invention result from the simple and efiectivemechanism by which the carrying-table is moved up and down in parallelplanes without tilting, so that the machine need not be firmly securedthereto, as in constructions where the carrying-table is tilted inclosing the desk. This movement is obtained without any complicatedconstruction of pulleys and connecting-cords, and the movements arepositive and the parts not liable to get out of order.

Many changes may be made in the form and arrangement of the mechanismfor moving the carrying-table without departing from my invention, sinceI consider myself the first to provide mechanism by which this table ismoved in parallel lines without the use of flexible-cord connections.

I claima 1. The combination with a desk or table having a tilting topsection, of bell-crank levers pivoted to the desk, one arm of each leverbeing pivotally connected to the front portion of the top section, amachine-support having vers pivoted to the desk and pivotally 0011-;nected with the front portion of the top section, a machine-carryin gtable, bent or curved links pivotally connecting the bell-crank leversto said machine-table, and links pivotally connecting the rear portionof the tilting' top With the desk, the machine-table moving verticallyin parallel planes as the top is tilted; substantially as described.

3. The combination with a desk or cabinet having a tilting top, ofliftinglevers fulcrumed to the desk and pivotally connected with thefront of the tilting top, a machinetable and link connections betweenthe levers and said table, arranged to move said table vertically inparallel planes; substantially as described.

4. The combination with a desk or table having a tilting top section, oflifting-levers f ulcrumed t0 the desk, and pivoted to the tilting topsection, a machine-table having link connections With the leversarranged to move the same vertically in parallel planes, and a stoparranged to contact with the lever mechanism and hold the table firmlyin place at the upper position thereof; substantially as described.

In testimony whereof I have hereunto set my hand.

EDWARD E. BAKER.
